Be it known that I, CLAES Osoan Mii-URK, a citizen of the United States,`residing at Los Angeles, in the county of Los Angeles and VState of California, haveinvented certain new and useful Improvements in Cooler l-oxes, of which the following is a specification.

My invention relates to cooler boxes, and the objects are first, to provide a self cooling container and storage place in a chamber for food and other perishable materials; second, to provide a storage box with a self contained Ventilating system; and third, to construct a cooler box that is simple in construction and inexpensive to maintain. Y

Other objects and advantages will be made manifest in the following specification with an embodiment of the invention illustrated in the accompanying drawings, in which:

Figure 1 represents a side sectional view on line 2-2 of Figure 2.

Figure 2 represents a plan sectional viewk on line 1-1 yof Figure 1. Y

Referring to the drawings in which like characters of reference designate rsimilar parts, the cooler 15 comprises an outer-box 1 and an innersbox 2, the inner-box 2 being secured in the outer-box 1 to provide a chamber 3, in the rear, side and top portions of the said cooler 15, as shown in Figures 1 and 2, and the chamber 4 is in the inner-box 2, and the chamber 4 is in communication with the chamber 3 through the passages 9-921, chamber 14 and the passages 11-111, respectively, and the chamber 3 is in communication with the outside portion of the cooler 15 through the passages 10-10"-, Vchamber 13 and the passages 8-8a, respectively. The said chamber 13 is positioned in the pocket 6, and the pocket 6 is se-cured to the upperinner surface of the outer-boxl within the said chamber 3, and the pocket 7 is in turn secured to the' upper-outer surface of the inner-box 2 within the chamber 3, as shown in Figure 1. The said passages 9 9a pass through the rear wall of the said inner-box 2 at an angle to one another and point from a parted position in the inner face of the box 2 to a relatively closer position in the adjacent face of the pocket 7, and the passages 11-11a in turn pass downwardly through the pocket 7 from the chamber 14 to the space 3. The passages 10-10a pass from the chamber 3, through the pocket 6, tothe chamber 13, andlthe passages 8 8 pass through the rear wall ofthe said outer-box 1 atan angle to one another, and pointfrom a parted position in the outer face of the boxll to afrelatively closer position in the adjacent face o-fthepocket 6. Y

A' door 12 is operatively positioned in the front portionofthe cooler 15, and the outerbox 1 andinner-box 2 are elevated from the floor line by legs 16 to provide a space 5 thereunder. 1

When air currents pass the rear portion of the cooler 5, as indicated by the arrows, air passes through passage 3 into pocket 6, then from pocket 6 through passage 10EL into chamber 3, through one side of which chamber Vthe air circulates and thenl passes throughpassage 11au into pocket 7, then from pocket 7 through passage 9 into box 2 where the air circulates throughout and then passes out through passage 9a into pocket 7, then from pocket 7 through passage 11 into chamber 3, through the other side of which chamber the air circulates and then passes through passage 10 into pocket 6 and then from pocket 6 through passage 8a back into the atmosphere.

When the air current passes the rear portion of the cooler in a direction opposite to that indicated by the arrows, air passes `through passage 8a into pocket 6, then through passage l0 into chamber 3 through one side of which the air circulates and then passes through passage 11 into chamber 7 then through passage 9a into storage box 2 where the air circulates throughout and then passes through passage 9 into pocket 7, then through passage 11a into chamber 3, through the other side of which the air circulates and the air passes through passage 10a into pocket 6 and then through passage A3 back into the atmosphere.

Having thus described my invention what I claim is:

1. A cooler box comprising a storage chamber, an air circulating chamber partly surrounding said storage chamber, a pocket on the outer wall of said air circulating chamber, said pocket being provided with a pair of angularly disposed air passages communicating with the atmosphere land with a pair of air passages communicating with said air circulating chamber, a second pocket on the wall between said storage chamber and said air circulating chamber, said second pocket being provided witha pair of passages communicating with said air circulating chamber, and with a pair of angularly disposed passages communicating with said storage chamber.

2. A cooler box comprising a storage chamber, an air circulating chamber partly surrounding said storage chamber, a pocket on the outer Wall of said air circulating chamber, said pocket being provided with a pair of passages communicating With the atmosphere and with a pair of passages oommunicating with said air circulating chamber, a sec-ond pocket on the Wall bet-Ween said storage chamber and said air circulating chamber, said second pocket being provided with a pair of passages communicating with said air circulating chamber, and

with a pair of passages communicating with said storage chamber.

3. A cooler box comprising la storage chamber, an air circulating chamber partly surrounding said storage chamber, a pocket on the outer Wall of said air circulating chamber, said pocket being provided with a` pair of passages communicating with, the atmosphere and with a pair of passages communicating With Vsaid air circulating chamber, a second pocket belo-W said iirst pocket on the Wall dividing said chambers, said second pocket having a pair of passages communicating With said air circulating chamber and with a. pair of passages commuicating With said storage chamber.

In testimony whereof I aliix my signature.
